Consumer Mods Integration Guide

Overview

This guide details how third-party mod developers and collection addons can integrate with Stack Size Adjuster to define specialized stack limits or inspect active categories.

🛠️ Step-by-Step Addon Integration Guide

Step 1: Add Mod Dependency in fabric.mod.json

Add stack-size-adjuster to your mod's depends or suggests block:

"depends": {
    "stack-size-adjuster": ">=1.4.16+26.2"
}

---

Step 2: Register a Custom Stack Size Override

In your mod's ModInitializer, call StackSizeManager.registerOverride:

package com.example.addon;

import net.fabricmc.api.ModInitializer;
import net.instantgratification.stacksizeadjuster.util.StackSizeManager;
import net.minecraft.world.item.Items;
import net.minecraft.world.item.SplashPotionItem;

public class ExampleAddonMod implements ModInitializer {
    @Override
    public void onInitialize() {
        // Register custom stack size rules for splash potions
        StackSizeManager.registerOverride((item, originalSize) -> {
            if (item instanceof SplashPotionItem) {
                return 8; // Custom limit of 8 for splash potions
            }
            if (item == Items.TOTEM_OF_UNDYING) {
                return 16; // Allow totems to stack up to 16
            }
            return originalSize; // Unmodified items retain category GameRule limits
        });
    }
}

Step 3: Query Active Stack Size Limits Programmatically

To query the currently active limit for a specific item programmatically:

import net.instantgratification.stacksizeadjuster.util.StackSizeManager;
import net.minecraft.world.item.ItemStack;

public class StackQueryUtil {
    public static int getEffectiveLimit(ItemStack stack) {
        int original = stack.getMaxStackSize();
        return StackSizeManager.getModifiedStackSize(stack.getItem(), original);
    }
}
